Experimental Research On Directional Transport Device Of Corn Combine

Corn is one of China's major food crops, annual planting area in China has reached 30 million hectares, but the harvesting rate by machine was not high , mechanization has been slow. For domestic corn combine harvester, those are divided into straw type, straw recovery type, harvesting silage type and so on. With the development of society, market demands for more diverse: in some areas require harvesting and straw; some areas require snapping peeling at the same time; animal husbandry demands a good stalk shredding and recycling; new power plants and recycling paper demand for requirements of new straw. So now the direction of development of domestic corn harvest model is: has the Harvesting, peeling, ear collection, straw directed placement (or chopped recycling, or shredding into field) of the corn combine harvester. Face to such a diversity of models, designing a new straw recovery corn harvester became a urgent problem for researchers.Directional transport device as the research objects, the indoor experimentation was conducted in indoor test-bed. With once cut rate and average inclination for the experimental indices, cutting performance experiment was tested to analyze influence orderliness of the crank speed of cutting knife. The use of high speed photo, the impact of horizontal transport properties of the main parameters was analyzed .Aim at the questions of transverse transporting device of new corn combine harvester, conducted through the single factor experiment of the length of under poking tooth and the angle of under poking tooth, the influence orderliness was obtained with the corn transporting rate. An orthogonal test of three factors was carried out to find the optimized parameters suitable for the properties target .The continuity experiment of the corn transporting was made to verify suitability of the optimized parameters. with corn transporting rate for the indices ,the test of vertical transmission performance was done to analyze influence orderliness of belt speed of vertical upper poking tooth and under poking tooth on corn transporting rate. The research provides a basis for the optimal design of cutter device, horizontal conveyor and vertical conveyor.
